| Abstract: | In accordance with the reqirement of separated transmission and detection of DC voltage with high accuracy in 4-R system,a new sensor,based on the Magnetic-balance principle of Hall Effect and proportion-control circuit,was designed,proving of high accuracy,satisfactory linearity,low shift of temperature,and constant adjustability of the transmission proportion. The comparison with optoelectronic sensor revealed that the sensitivity accuracy of the new design was raised 28 times even worked in an environmen |
